Rui was walking to Tsukasa’s house… he had gotten a call not that long ago from Saki, Tsukasa’s sister, that Tsukasa was sick and was hoping that Rui could take care of him. He agreed and that’s why he’s walking right now..

When Rui got to Tsukasa’s place, he knocked, but the door opened.

‘Saki must have left and kept the door unlocked for me..’ Rui smiled and walked in.
